This is the wooden construction kit that allows children to build 20 life-size ride-on models such as a 63" tall working crane. Young engineers use the 26 solid pine posts with pre-drilled holes, steel bolts, and 7 1/2"-diameter wheels to build a go-kart, tricycle, or a rolling airplane they can ride on. Many of the models have moving parts, allowing children to hoist obects from the seat of the crane, rotate the plane's propeller, and turn the handlebars on the scooter they've constructed. Steel cap nuts and plastic washers help ensure structural integrity and 13 plastic panels with pre-drilled holes provide flat surfaces ideal for a chair's seat and backrest, an art easel, or the base of a wagon. Includes two combination wrenches and an instruction manual with detailed, step-by-step illustrations. Ages 5 and up. (34 lbs.)
